In the veil between organic and inorganic semiconducting materials a hybrid class of organometallic perovskites (generic formula ABX3) has emerged as one of the most promising novel systems for highly efficient photovoltaic applications (world-record: 25.2 %, early 2020). The origins of some of the extraordinary properties (e.g. extremely low loss in open-circuit voltage) of the solar cells along with practical issues (long-term stability) remain to be solved.
The Perovskite Group at the University of Potsdam aims at the development of highly efficient, stable single and multi-junction perovskite cells through a fundamental understanding of charge transport and recombination processes. Visit the homepage of the Perovskite subgroup and find out more of our current research efforts to understand this exciting solar cell material or write us an email (firstname.lastname@example.org)! We are also part of a joint graduate school (HyPerCells) between the University of Potsdam, the HU Berlin and the HZB. Here we combine a manifold of techniques to study fundamental properties of the perovskite materials as well as their viability to work in conjunction with commercially available solar cells (e.g. Silicon) in so-called tandem-solar cells.
